Why is the surface tension of heavy water less than light water?

WebThe linear thermal expansion coefficients of ice and heavy ice single crystals were measured in both hexagonal crystallographic axes between the melting point and 18°K. The expansion coefficients of H 2 O and D 2 O become negative below 63°K. Authors: Dantl, Gerhard Publication Date: Thu Feb 01 00:00:00 EST 1962 Research Org.: Heavy water (deuterium oxide, H 2O, D 2O) is a form of water that contains only deuterium ( H or D, also known as heavy hydrogen) rather than the common hydrogen-1 isotope ( H or H, also called protium) that makes up most of the hydrogen in normal water. The presence of the heavier hydrogen … See more Deuterium is a hydrogen isotope with a nucleus containing a neutron and a proton; the nucleus of a protium (normal hydrogen) atom consists of just a proton. The additional neutron makes a deuterium atom roughly twice … See more The physical properties of water and heavy water differ in several respects. Heavy water is less dissociated than light water at given temperature, and the true concentration of D … See more Different isotopes of chemical elements have slightly different chemical behaviors, but for most elements the differences are far too small to have a biological effect. In the case of … See more On Earth, deuterated water, HDO, occurs naturally in normal water at a proportion of about 1 molecule in 3,200. This means that 1 in 6,400 hydrogen atoms in water is deuterium, which is 1 part in 3,200 by weight (hydrogen weight). The HDO may be separated from … See more Semiheavy water Semiheavy water, HDO, exists whenever there is water with light hydrogen (protium, H) and deuterium (D or H) in the mix. This is because hydrogen atoms (hydrogen-1 and deuterium) are rapidly exchanged between water … See more The US scientist and Nobel laureate Harold Urey discovered the isotope deuterium in 1931 and was later able to concentrate it in water. Urey's mentor Gilbert Newton Lewis isolated the first sample of pure heavy water by electrolysis in 1933.
